Deutsch ist schwierige aber ich geneße es. I joined a crash course German class and I'm documenting it in a blog after every class. Now, I'm trying to write my first post in Deutsch, just a very simple one, but I'm having a bit of a hard time which word to use for the following:

About
Etwas oder Über?

Lesson
Lektion oder Unterricht?


My sentence is this: Unsere Deutsch Lehrehrin ist sehr freundlich. Aber unsere Lektion ist mehr ... [I'm not sure about the second one because that's where I'm having difficulty in. I'm meaning to say: "But our lesson for today is about numbers and it is more difficult than I have expected."] Can anyone help me out with this? :) It's only my third day in Deutsch class, I'm quite enjoying it.
